What is no.4 stainless steel coil?

No.4 stainless steel coil is a universal stainless steel finish. People extend evenly along the length of the coil. Moreover, people use abrasive machinery to polish and finish stainless steel. And then people use 120-320 grit sandpaper for polishing. In this way, a small amount of metal on the surface can be removed without affecting the thickness of its stainless steel. In this way, people made the No.4 stainless steel coil.

Product Details

The production process of No.4 stainless steel coil

There are very fine refractory materials in the abrasive belt. Such as silica, alumina.

Polishers in stainless steel plants lubricate the cutting action by filling the strip with oil. So,this helps keep it cool and provides a finer, more uniform surface.

Because the production process is variable, not every No.4 finished product looks the same. Sometimes, different manufacturers of abrasive belts have different grain sizes. So the service life of No.4 stainless steel coils is also different.

When people choose the No.4 stainless steel coil, its appearance must match the job requirements. Therefore, a project should use the same batch of No.4 stainless steel coil material package.

By the way, compared to 2B or BA finishes, No. 4 is easier to achieve a reasonable appearance match.

And, when using it, follow the direction of the polishing line of No. 4 stainless steel coil.

Compared to 2B or BA finishes, No. 4 is easier to achieve a reasonable Moreover, No. 4 finishing is easier to achieve a reasonable match in appearance.
